"Speed" problems with OpenGL apps?

Hi =) I have made some OpenGL programs, and, uhm, they run perfectly on my computer. But when they run on a new computer / a fast one, they run too fast! I mean, it's like the processor works so fast that the objects move too fast, and too much.

I hope you get my point, and if I could use like a timer that you use with WinAPI, it would be pretty easy, right?
